    Problem audio in webcam, carton and or smurf voice

    Hello.
    I have a webcam and the few days ago, I try to made a video conference.
    The other person, can view at me well, but the audio...very slow and like a carton network (quick voice and smurf).
    After, I try to record the voice with webcam in audacity, and yes, the voice is like carton / smurf.

    I review all but I don't view how or where are the problem.

    Thanks and regards.

        A couple things to try :
        See if turning down the recording volume a little clears this. Another is to run the alsamixer command, hit F6, and select the USB audio device, then F4 to select capture (input). Look to see if there is a mic boost setting, and turn that down or off. This sometimes helps with this problem. Also make sure that your recording is from the cam's mic and not the system's mic. If you prefer that over the cam's, check the level on that, and any mic boost as well.

          But does not say which step fixed it (this may be outdated for 18.10 anyhoo)
